How difficult to generate Fortran dll's?

[ctlin]

i have about sixteen '.f' files and a few '.com' files. most of the .f files have several subroutines in them that do math algorithms and simple i/o to the terminal. all of these files make one program i think.

how do i go about breaking this thing into dll's so that i can control the flow of the program from visual basic? does each '.f' file equal 1 DLL? Do I divide all the subroutines into their own DLL's? i realize that this is a pretty vague description of the program but i need general answers regarding the difficulty of converting a whole fortran program into something that can be run with a VB front-end. please help. thanks.

If you are using compaq visual fortran, create a DLL project and include all the fortran files in it. Since you are using VB as the front end, you probably wont need the files doing io to the terminal.

Hope this helps. CaKiwi
